Application led December 1, 1925. Serial No. 72,580. I

This invention relates to metallic roofing shingles, and the general object of the 1nvention is to improve upon the shingle illustrated in my Patent No. 1,432,999, granted October 24, 1922, and particularly to so construct the shingle that any water getting into the lock between one shingle and the next adjacent lateral shingle will not run over the edge of the lock, causing leakage, but will run out or down onto the shingle immediately below and so down to the exterior of the roof.

A further object is to provide interlockin anges on the lateral margins of the shingles whichwill permit .the shingles to be readily engaged with each other and which, when interlocked, will provide rainproof joints between the shingles, and further to so construct the shingle as to prevent the entrance of water at the lower ends of the beads.

My invention is illustrated in the accompanying drawing, wherein Figure 1 is a fragmentary top plan View of a series of shingles constructed in accordance with my invention and applied to a roof;

Figure 2 is a section on the line 2-2 of Fi 1' Figlire 3 is a like section to Figure 2 but showing the adjacent marginsof the two plates separated;

Figure 4 is a section on the line 4-4 of Fig. l;

Figure 5 is a like view to Figure 4 but showing the two parts separated;

Figure 6 is a fragmentary perspective view of the lower corners of two adjacent shingles, the shingles being separated;

Referring to the drawing, it will be seen that each shingle consists of a sheet of metal 10 which is preferably of zinc, though it might be made of any other desirable metal and of any suitable gauge, each shingle being formed with a, side ange, as will be later described. These side anges 'terminate short of the upper end of the shingle and this upper end of the shingle is bent downward upon itself, as at 11, below the top of the shingle, then again bent upon Aitself and extended upward above the top of the shingle, as at 12, this attaching flange so formed being perforated for the passage of attaching nails, as at 13. The lower edge of the shingle is formed with a flange which extends downward, as at 14, and then inward, as at 15 this flange on one side terminating short of the correspondin lateral bead, as at 16, and on the other si e being cut away as at 17. One side margin of the metal sheet forming the shingle is bent inward between the body of the shingle, as at 18, and then is bent downward and upward to form a trough 19, the upper edge of this It will be understood that the shingles are laid as illustrated in Figure 1, with the bead 20 extending upward and the gutter or trough 19 downward, the flanges 12 being nalled to the roof sheathing- After one course of shingles has been laid, an upper course 1s laid by engaging the inturned anges 15 with the portions 11 in the manner illustrated inl Figure 4, so that the nails of the course below ,are entirely covered by the shingle above. Of course, the upper row of shingles is laid to break joint with the lower row in the usual manner.

The lateral margins of the same course of shingles are interlocked with each other, as illustrated in Figure 2, that is, the ila-t marginal portion 21 is inserted beneath the outstanding bend 18 and over the trough 19 and then the shingle which is so inserted is turned down into a position against the roof or sheathing and forced laterally inward until the edge of one shingle bears against the under face of the bead 20 of the other shingle; Under these circumstances a trough or glitter 19 is provide which extends down the entire length of the shingle and is disposed between two shingles, while the outer wall of the trough 19 extends slightly above the 4level of the shingle itself and bears tightly against the under face of the bead 2() of the next adjacent shingle.

Inasmuch as the flange 14 is cut away at 16, and 17, it follows that any water which may collect in this trough will run downward and be discharged onto the outer face of the shingle below so that any water getting into the lock and more specifically into the gutter 19 will not run over the edge, causing leakage, but will run downward in this gutter or trough onto the shingle below;

It will be seen from Figure 2 that the margin of the trough 19 extends upward into the bead 20 about a quarter of'an inch higher than the face of the shingle, thus preventing any chance of the water overflowing over this edge and thereby leaking. I have found in actual practice that this practically does away with any leakage between the shingles even in violent storms where ordinarily water is liabl to beat in, and that the roofing so forme is particularly effective.

1. A metallic shingle of the character described vhaving on one lateral margin thereof anupwardly convex, longitudinally extending bead and a flat portion beyondthe head and the other margin thereof having the metal of the shingle inwardly bent wall of one shingle being adapted to fit within the bead of the other shingle.

2. A metallic shingle comprising a rectangular sheet of metal, one side margin of the sheet being formed to provide an upwardly convex, longitudinally extending bead, the opposite margin of the sheet being formed to provide a longitudinally extending, transversely concave trough depending below the lower face of the shingle and having an exterior wall extending above the level of the upper face of the shingle and adapted to extend into the bead o the next adjacent shingle, the trough constituting a longitudinally extending gutter conveying water upon the face of the shingle next below.

l In testimony whereof I hereunto aix my signature.
